RMCE replaced the floxed luciferase gene in Gt(ROSA)26Sortm1Dwir with an inverted fusion protein of the hsp 73-capturing N-terminal viral J domain of SV40 T-Ag (cT77); 108-residue of the Ovalbumin fragment (aa 246-353 with a isoleucine to valine change at position 258) with well-characterized Kb- and Ad/b-binding epitopes (specifically recognized by OT-I or OT-II/D011 TCR), and the eGFP reporter. Cre-mediated recombination is required to achieve expression of the fusion protein. (J:173806)
